Fila had comfort and performance in mind when producing the r8. Blending comfort and function in the upper, there is plenty of support using a combination of synthetic and mesh materials. The toe wrap made up of Fila's Duracera II, provides the necessary toe durability for even the worst toe drag offenders. In the midsole, PolyAction in the forefoot combined with Super Action in the heel make for comfortable and protective landings on court. The EverGrind outsole offers the durability needed for hardcourt enthusiasts while the modified herringbone pattern provides sure footed traction. This performance shoe from Fila comes with a 6-Month Durability Guarantee.
